Naruto: Ultimate Ninja Heroes 2: The Phantom Fortress is a mostly recycled fighting game placed within a hollow adventure.

To lay its basic contents bare, this game contains a lengthy single-player campaign called The Mugenjo, a series of team battles called Heroes mode, a head-to-head battle, a bonus content area called Ninja Road, and finally, Naruto's House, where you can view purchased bonus items.

It's a ton of content, and it would take you well over 10 hours to explore all of it. It will take you only about two hours, though, to get tired of it.

The single-player campaign, The Mugenjo, takes place in the Phantom Fortress. This floating palace of doom is 99 stories tall, and each story contains several rooms and stairs.

For instance, when you take the stairs up from the third floor, you'll find that there are two or three rooms between you and the stairs up to the fifth floor. In all likelihood, the two or three rooms in front of you will be blank. This means you need to "summon" a room through which to travel.

To do this, you need to use a room-summoning scroll. At any given time, you have four of these, and when you use one, it's replaced by another at random.
